The role and what you’ll be getting up to on a day-to-day basis:

As a Network Engineer at Littlefish, you’ll provide proactive 3rd line support across our Network and Firewall technology stack within our support remit. You’ll be comfortable working independently to resolve client issues, including communicating clearly with non‑technical colleagues and customers. We value calm, evidence‑based thinking — especially when investigating incidents and identifying the right fix. Most of your time will be spent resolving inbound technical issues (some of which will be complex or sensitive and require special handling), and from time to time you’ll support major incidents affecting your clients. Outside of incident resolution, you’ll also deliver requests and changes, help other engineers with tricky problems, and take part in continuous improvement activities that strengthen how we operate.

You will:

• Provide proactive 3rd line support for Network/Firewall technologies within the Littlefish support remit
• Where you have the skills, support additional technologies (e.g., Infrastructure Cloud/On‑Prem related issues)
• Act as a technical escalation point for internal technical teams
• Work with Service Managers / Service Desk Manager on escalated issues
• Provide technical expertise and resource to projects and transitions
• Monitor and progress incidents, changes and requests assigned to you
• Help maintain service levels across the team (including SLA/KPI performance)
• Provide support, coaching and mentoring to team members in your areas of expertise
• Play an active role in operational acceptance, defining standards, processes and procedures
• Create and maintain knowledge base articles around core internal and customer technologies

Who you are:

You’re a hands‑on network engineer with a strong technical foundation who enjoys solving problems, taking ownership, and delivering great customer outcomes. You’re confident working independently, know how to communicate clearly with technical and non‑technical audiences, and you’re calm and methodical when pressure is on.

You will have:

• Proven experience working as a Network Engineer, ideally within an MSP or multi‑customer environment
• A solid technical foundation across routing, switching, firewalls and network security
• Hands‑on experience supporting enterprise networking technologies such as Cisco, Juniper or Fortinet
• The ability to investigate and resolve technical incidents independently using clear, evidence‑based thinking
• Confidence communicating with both technical and non‑technical colleagues and customers
• Experience producing high‑quality technical documentation, SOPs and diagrams
• A calm, organised approach with the ability to manage priorities and perform well under pressure

What can we offer you?

• Healthcare cash plan. This will give you access to online GP appointments, 24/7 access to qualified counsellors and cash back against a range of general healthcare
• Referral bonus scheme of £1000 when you successfully refer a friend.
• Access to our LinkedIn Learning platform, with over 16000 expert‑led online tutorials to enhance and achieve your personal and professional goals.
• Casual dress policy
• Company Pension Scheme
• Company social events
• 25 days annual leave plus public / bank holidays
